Is it hard to make money in the US stock market? Yes.

Is it easy to make money in the US stock market? Yes.

1. Don't be too arrogant. Your investment experience isn't that impressive. Admit that others are better than you. For example, cola, Value Brother, and Uncle Bird. Their stock-picking vision is on a different level from yours or mine, and they love to help and share. I'm truly grateful.

2. Find excellent people and listen to them when you disagree.

3. Buy at the right price, leave enough margin of safety, and follow the big players' bottoms.

4. Control your position size. Whether you're buying or following others, don't go all in. You don't know the big players' capital or positions. If you follow their watchlist, you'll need money to follow when they average down.

5. Don't act impulsively. I sold half of my small rocket position, 2/3 of CLF, and lost $100K on Berkshire Hathaway because I didn't hold the options. Remember, even the best investors in the world don't have to trade every day. Trading isn't clocking in—no need to force a trade daily.

6. If you follow someone, trust them. Don't believe them when the market rises and doubt them when it falls. Also, take responsibility for your actions. You don't share profits with the big players, so why complain when you lose money?

7. Buy more stocks and fewer options. Many people buy options without even knowing what volatility is—myself included.

8. Don't try to catch the last penny. If you didn't trim when Xiaomi rose from 30 to 58, you're just waiting to get burned. Knowing when to take profits is an art. Learn to exit without regret using pyramid position-sizing to lock in gains.

Well, I've been lucky lately. But I'm still down $3K over the past three months. Keep pushing.$Alphabet - C(GOOG.US)$Unitedhealth(UNH.US)$Taiwan Semiconductor(TSM.US)$NVIDIA(NVDA.US)$Rocket Lab(RKLB.US)$Amazon(AMZN.US)$Cleveland Cliffs(CLF.US)
